I remember seeing those "try before you buy" racket rental before, however i can't seem to find it now, was it from WinningCycle? perhaps they taken it off their website, are there any other vendors out there provide this kinda thing? thanks.

I heard Yo's Sports has this service.
They allow you to demo a racquet for $5 a day.
If you end up buying a racquet from them, the demo fee will be deduced.

I read it from here long time ago. You should call them to check it out.

Welovetennis in Brampton has this service.
It is $5 deposit.

Brown's Sports does it, $10/day and if you buy a racquet from them, you get the $10 off. It's abit steep compared to Yo's though in terms of price.

any other store in US ???
